The best way to show you're worried about a competitor is to copy their product and attempt to do it better than the original. Facebook is obviously worried about Snapchat, because it's created not one, not two, but three Snapchat clones over the past few years. Now it's got another one, Flash, aimed at emerging markets.

We've known WhatsApp would be enabling 2-factor authentication for many months now, but the functionality has only just gone live in some of the latest beta versions of the app (2.16.341 and above, maybe even earlier).

If you head over to your account settings in WhatsApp, you'll see a new Two-step verification option. Tap it to get to a screen that explains what 2-step verification is and get the option to enable it.

Hopefully you're not sick of hearing about Daydream just yet, because the line of apps supporting it at launch is still growing. There's a new version of Play Movies & TV rolling out to users, and while you can't see the evidence in the UI just yet (at least I can't), it joins in the parade of apps that give the new and improved virtual reality viewer something to do. But this teardown also brings a few additional treats and unexpected details. As always, you can grab the latest apk from the download link at the bottom.

Viber is one of the many apps trying to supplant traditional phone calls and texts. But to achieve that dream, the service can't stop with connecting you to friends and family. You need to get in touch with stores and other businesses too. That's why the latest Viber update introduces public accounts.

Depending on where you're at in the world, you may have some holidays coming up that demand long drives and a lot of time watching a screen as Google Maps directs the way back to family. There's a new update out that might make your trip planning and navigation just a little better. Version 9.41 has a new option to always start up in satellite mode, adds links to articles about top-listed businesses, and polishes the look for adding stops along a route. There are also hints that it will show when a hotel is running a good deal.

Users of Adobe's Android app have been able to process RAW images in the company's DNG format for a while, but the new update to v2.2 adds much more robust RAW processing. You can directly import RAW files from your camera, edit them, and export to all your devices.

In preparation for the launch, there are new apps and games available on the Play Store that are compatible with Google's new virtual reality platform. Here are the ones we've already discovered; let us know if there are more that we haven't mentioned.
